Re: APOD: A Dust Devil of Mars (2012 Apr 13)
Air - A colorless, odorless, tasteless, gaseous mixture, mainly nitrogen (approximately 78 percent) and oxygen (approximately 21 percent) with lesser amounts of argon, carbon dioxide, hydrogen, neon, helium, and other gases. Nope, no "air" on Mars since it has an atmosphere composed of rou...

Re: APOD: The Leo Triplet Galaxies from VST (2011 Aug 03)
Why is APOD repeating the entry from March 6, 2009? Was it a slow day for astronomy? ![Very Happy :D](./images/smilies/icon_biggrin.gif)

I am looking forward to July 2015 to see what other wonderful discoveries are made by New Horizons. Just think of the other discoveries that might be shared on APOD between now and then. Four years worth! Keep on truckin' APOD!

Re: APOD: Hydrogen in the LMC (2011 Apr 26)
Like NoelC, I also wonder what the view of the Milky Way would look like from the LMC. Would a viewer within the LMC see us edge on, tilted, or more face on? How bright would we appear to "them" and how many degrees would we span in "their" sky? Has anyone ever done an artist's r...

Re: APOD: Earth and Moon from MESSENGER (2010 Sep 01)
Is it possible that the brighter object being discussed could be Andromeda? I am not clear on where in the constellations that Earth and the Moon appear, but I do think I recognize Perseus near the top center of the picture, just above and to the right of the Earth-Moon combo.

Apparent Motion of Distant Objects
I am an avid APOD viewer. I was wondering about how fast things are moving in the universe and how we might perceive apparent changes in location or appearance of distant objects. Has anyone ever done comparisons as to how objects in the universe appear now as compared to when they were first imaged...
